Abstract: The harvesting of castor is highly seasonal and labor-intensive, necessitating a reliance on mature mechanical harvesting equipment. Castor harvesting machinery is a weak link in the castor industry chain, severely constraining the development of China’s castor industry. This article elaborates on the current status of the castor industry and the harvesting modes, which mainly include combined harvesting and segmented harvesting. It systematically summarizes the harvesting platforms, cleaning technologies, and shelling technologies of castor harvesting machinery in China and internationally. It analyzes the main structural forms and working principles of the harvesting platforms of castor harvesters. The cleaning technologies and different types of shelling technologies of harvesters are also analyzed and summarized. Finally, this article identifies the existing problems in castor harvesting in China and provides an outlook on future development trends. It suggests that China’s castor cultivation will strengthen the integration of agricultural machinery and agronomy, while harvesting will develop in the direction of combined harvesting. In the future, the focus will be on the development of high-efficiency harvesting, specialized low-loss shelling machines, and breakthroughs in key core technologies to promote the development of mechanized castor harvesting technology in China.
